SimCP2 contains four electron-donating carbazole groups with two mCP units (a well known host material) joined together by a diphenylsilane link. The mCP joined structure makes SimCP2 more robust to support the growth of high quality thin films, and it is also believed that the rigid structure can enhance the lifetime and color purity of OLED devices with high luminance.
SimCP2 also possesses a wide triplet band gap (ET = 3.0 eV), high carrier mobility, ambipolar transport property and high glass transition temperature (Tg = 148 °C).
The solution processability of SimCP2 also gives it an advantage in device fabrication, where it can be used to enable higher device efficiency with homogeneous distribution of the host and guest in the emissive layer.
